Abstract (en)
[origin: EP0385346A2] A spatial light modulator has a photoconductive layer (4A) deposited on one glass substrate (1A) having a transparent electrode. A first liquid crystal alignment film (5A) is formed on the photoconductive layer (4A). A second liquid crystal alignment film (8A) is formed on another glass substrate (2A) having another transparent electrode. A ferroelectric liquid crystal (10A) is filled between the first and second liquid crystal alignment films (6A, 8A).
